Existing reviews of Portable Hydrogen (H2) Gas Detector, 0 to 500/1000/2000 ppm
Portable and easy to operate, it is really helpful in my work.
Bought this gas detector for work. It isn’t cheap, but works well. Portable and easy to operate, it is really helpful in my work.

Dear Noah, thanks for your ordering and comment. To ensure the accuracy of the measurement, our gas detectors adopt the high-performance sensor so the cost is relatively higher. Good gas detector deserves this price.
Inquiry for Hydrogen (H2) Gas Detector

Yes, we can provide this H2 detector with the measuring range of 0-10ppm and the resolution of 0.001ppm.
Does your H2 gas detector continuously check the hydrogen leakage automatically or we need to check it manually?

This detector can continuously check the hydrogen leakage automatically.
Hydrogen gas detector 0-100%VOL
Can we use your hydrogen gas detector to measure hydrogen in Air via selecting 0-100%VOL measuring range?

No, the range 0-100%VOL is usually used to measure the purity of H2 in a single gas, so it is not suitable for measuring H2 in an air mixture.
Using H2 leak detector for refrigeration piping system
Hi. We are a chiller manufacture and we currently use a 95-5 nitrogen-hydrogen gas mixture to pressurize and leak test our refrigeration piping systems. We use the H2 leak detector to find out the leaks and was curious if you had any experience using this equipment for that purpose?

Hi, Jed. You are welcome, but sorry to tell you, our portable hydrogen gas detector does not support H2 leaks test of refrigeration piping systems.
A technical inquiry regarding your portable hydrogen gas detector (0-2000ppm)
Hi. I have a technical inquiry regarding your portable hydrogen gas detector (0-2000ppm): what other gases can cause interference with the detection of hydrogen in this sensor? For example, we'd like to monitor hydrogen (0-2000ppm) in an exhaust gas stream that contains 73% N2, 12% O2, 10% H2O, 5% CO2, 2000ppm CH4, 500ppm CO, 500ppm NO and 750ppm NO2. Would the detector foul with these gases present?

Hello, Scott. In your case, CO will interfere with the H2 detection. If there is 500 ppm of CO in the environment, then even if no H2 exists, the H2 gas detector reading will show 2000ppm.

Hi, Gavin. It can detect 2 ppm at least.
Can we buy the H2 gas sensor head separately if needed in the future?

Yes, you can but the price is approx 80% of the whole sensor price.
What is the frequency of calibration required for your H2 gas detector?
Hi. What is the frequency of calibration required for your H2 gas detector?
Can we do it locally? What is the cal gas you recommend?

Hi, Sam. For your questions, please check answers below.
1. Once a year.
2. Recommended gas for calibration is 1:1 hydrogen.
3. Yes, of course. You can perform calibration locally, by sending it to a local laboratory or calibration company for calibration. And we can send you the calibration operation video for your reference.
Suppose I want to operate your portable hydrogen detector while it is being charged.
Hi. Suppose I want to operate your portable hydrogen detector while it is being charged. Can I do that? The reason is that we do not want the battery to be drained so that the reading is wrong.

Hi, Herbert. We do not recommend operating the portable hydrogen detector while it is being charged, because it may cause unstable measurement. And our gas detector can generally be used for 20-30 hours after being fully charged.
If you want to monitor the gas continuously for a long time (more than 24 hours), we recommend using the fixed gas detector.
Hydrogen/methane detection
Hello there.
Since we only have a binary hydrogen/methane mixture and need to measure hydrogen, our thought was we could calibrate the unit using 100% methane as a zero or blank, and 100% hydrogen at the other end. The 2 gases have significantly different thermal conductivities, so as long your detector can provide accurate readings in such an environment, we can calculate the hydrogen vs. methane.

Hi, John. First of all, our Portable Hydrogen (H2) Gas Detector (0-to 100% VOL) is only suitable for measuring a single gas environment, so it does Not work in your case.
Then, we recommend using 0-100%VOL methane (CH4) detector (the lower limit of methane detection is 1%VOL), which can be used in different environments, and after the CH4 value is detected, then the remaining gas hydrogen can be calculated.
I'm interested to order the hydrogen gas detector (0-500pm)...
Hi. I'm interested to order the hydrogen gas detector (0-500pm) and therefore I got several questions.
a) Could you explain how the detection is carried out during a measurement/pump cycle?
b) What is the diameter of the air inlet of the portable detector system?

Hi, Gauri. You're welcome.
a) For the hydrogen gas detector, it has a built-in suction pump, so the gas inside the chamber will pass through the sensor continuously, and the gas concentration accurately appears on the display of the gas detector. At the same time, in order to avoid residues in the air chamber, the gas detector is designed with an air outlet.
b) The diameter of the air inlet is 5mm.
